Abstract: A riding toy includes a body with a spring assembly supporting the body on a base so that the body may be moved in first and second motions with respect to the base. The riding toy also includes a microcontroller and first and second motion sensors responsive to the first and second motions, respectively. The first and second motion sensors are positioned on the body and in electronic communication with the microcontroller. A sound synthesizing circuit is in electronic communication with the microcontroller and a speaker. The microcontroller is programmed to provide a first sound effect when the first motion sensor detects the first motion and a second sound effect when the second sensor detects the second motion. The first sound effect is varied based on a speed of the first motion and preempts the second sound effect if both the first and second motions are taking place simultaneously. The riding toy also includes a light sensor in electronic communication with the microprocessor.

Abstract: A sound producing play apparatus includes a support structure, an air compression system, a movable member, and a sound generating mechanism. In operation the air compression system harnesses energy from a user's movement of the movable member to create a forced supply of wind. The wind is then passed through a series of tubes and air reservoirs to a sound producing mechanism to create the desired sound. The air compression system includes an air compressor that is positioned inside a portion of the support structure to protect the air compressor from damage.

Abstract: An interactive ride-on toy, having a stuffed toy horse's head which includes ears, a movable mouth and is connected to a stick. One or more buttons, each with an icon depicting an image, is positioned on one or both ears of the horse's head. An electronically programmed chip responds to activation of the button to operate a speaker and a mechanism for moving the horse's mouth, the speaker playing sounds relating to the image depicted on each button.

Abstract: A motion sensing device for producing either an audio or a visual output includes a toy body, a motion sensor, either a sound generating device or a light generating device, and a control circuit. The motion sensor is coupled to the toy body. The motion sensor defines a cavity and has at least three contacts and a moveable object disposed in the cavity. The moveable object is positionable between at least a first position in which, the movable object bridges a first combination of two of the at least three contacts to form a first circuit input, and a second position, in which the moveable object bridges a second combination of two of the at least three contacts forming a second circuit input. The control circuit is coupled to the toy body and is electrically coupled to the motion sensor and to the generating device.

Abstract: A gas detector is disclosed which includes a CO sensor and a processor. The CO sensor senses an environmental CO concentration and provides a variable electrical output in response. The processor receives digitized samples of the sensor's electrical output and computes, with each measurement sample, a COHb level of a hypothetical person exposed to the CO concentration sensed. The computation involves determining an equilibrium COHb level for each measurement sample, which is compared with a previously computed COHb level associated with previously measured samples. The previously computed COHb level is updated based on the comparison. When the computed COHb level is above a predetermined danger threshold, the processor preferably causes an audible and visual alarm to be activated to alert any persons present. The gas detector can further include a CH.sub.4 sensor coupled to the processor for independently sensing CH.sub.4 levels such that an alarm is activated when the CH.sub.

Abstract: An apparatus is provided for use in connection with a child's toy which selectively generates a noise. The apparatus includes a chamber within a child's toy for holding a volume of air. Adjacent the chamber is a noise-making member, such as a reed, constructed to vibrate when subjected to a moving air stream. The moving air stream is created when the child sits on the toy and rocks back and forth (i.e., rides the toy). When the child rides the toy, air passes from the chamber and over the noise-making member. Surrounding the noise-making member is a tubular member for directing the air from the chamber around and past the noise-making member. The tubular member has an intake port in fluid communication with the chamber adapted to received air from the chamber and an exhaust port adapted to expel air after it has passed over the noise-making member.

Abstract: A laser oscillating apparatus equipped with a folded-type laser resonator designed to fold an optical axis by using a reflecting mirror (11) in addition to an output coupling mirror (4) and a rear mirror (10). The rear mirror (10) consists of a roof reflector having a ridge (10a) set at an angle of .pi./4 with respect to a plane generated by a folded optical axis. At this time, the reflectance of the rear mirror (10) is higher in a linearly polarizing component having an electric-field vector parallel to the direction of the ridge (10a) than that in a component having an electric-field vector orthogonally intersecting the ridge. The laser beam in the resonator is linearly polarized in the direction of the ridge (10a) in an optical path running between the rear mirror (10) and the reflecting mirror (11) closest to the rear mirror (10). The linearly polarized beam is reflected by the reflecting mirror (11). The reflecting mirror (11) generates a total .pi.

Abstract: A musical seesaw is provided and consists of a music box carried within hollow cylindrical post mounted on a base which is placed on a flat surface. When an elongated plank which is centrally carried between upper ends of a pair of spaced standards extending upwardly from the cylindrical post goes up and down, with a person riding on each end, the music box will operate.
